CAN-WASHING MACHINE.

To all whom it may concern Be it known that I, EDWARD MANivING, a

citizen of the United'States of America, re-

chines for washingcylindrical cans of all kinds; the Object being to provide a machine which is exceedingly simple and-Cheap inv construction and one 1n wh1ch a tank is employed in which the can to be washed is placed. and supported upon suitably 1 arranged brushes so constructed that the inside and outside of the can can be quickly washed; said brushes beingcontrolledxindependently in order to enable theoperator to causethe can to rotate with the inside set of brushes or to be held stationary by the outside set of brushes so that the inner and outer'surface of the can can be thoroughly washed.

Another object of my invention is to provide a can washingmachine with an expansiblebrush to receive the can and with movable brushes for washing the outside of the can together with meansfor operating said brushes so as to cause the can to be rotated with the expansible brush or tobe held stationary by themovable brushes.

Other and further objects and advantages of the invention :will be hereinafter set; forth and the novel features thereof defined by the In the drawings Figure 1, is a perspective of my improved can washing machine; Fig. 2, is a longitudinal'horizontal section showing the expansible' head in contracted position, the can being shownin dotted lines in position on the brushes; Fig.3, is a detail perspective of the rack members for operating the segmental gears formed on the ends of the brush-supporting arms; Fig. 4:, is a transverse section showing a can in position uponthe expansible head, the outside brushes being in their normal positions;

ill deizail enlarged elevation .of the expansible Like numerals of referencerefer to like parts in the several figures of the drawings.

In carrying out my invention, I employ a tank 1 which is mounted upon legs 2 and is formed at one end of a greater height, having a lunged cover 3 for closing thesame which is providedv with a centrally arranged opening for the purpose hereinafter fully described.

Extending out from the enlarged end of the tank is a bracket 4 provided with a bearing 5 in longitudinal alinement with a bear-..

ing 6 secured upon the end of the tank and mounted within said bearings is a shaft 7 wh1ch 1s provided with tight and loose pulleys 8 and 9 over which passes ,a drive belt 10, the shipper means for said belt not being shown, it, of course, being understood that any well-known formof shipper can be employed for shifting the belt from the tight to the loose pulley or .vice versa..

The driven shaft 7 extends into the en-'.

larged end of the tank and fixed thereon, is a heady 11 having spaced oppositely disposed lugs on the top and bottom faces of which are mounted arms 12 and 13 upon pivots 1 1 and 15 which extend through said lugs and plates 16 secured in position upon the top and-bottom of the head by bolts 17. The

plates are provided with centrally arranged longitudinally disposed enlarged. groove ortions 18 in which are mounted racks 19 and 20 which are adapted to cooperate with the segmental gears 21 and 22 formed respectively upon the arms 12 and 13, whereby said; arms'will be rocked upon their pivots as the racks are reciprocated so as to move the arms outwardly and inwardly for The rack bars 19 and 20 are carried by 1 guide rods 29 adjustably mounted. in bearings 30 formed on the collar 31 slidably mounted upon the driven shaft 7 said guide rods passing through guide eyes 32 of a sleeve 33 fixed on said driven shaft as clearly shown in Fig. 3; Surrounding the driven shaft 7 between the sleeve 33 and the collar31 is a coil spring 34 for returning the racks to their initial positions after they have been moved against the tension of said spring, as will be later described. The

sleeve 33'is provided with oppositely disposed lugs'35 on which are mounted links 36 which have their ends connected respectively to the brushes 23 and 24, as clearly shown, so that when the brushes'are moved outwardly, the inner ends thereof will be supported by said links.

In order to provide means for reciproeating the rack bars 19 and 20 to cause the brushes carried by the head to be expanded, a. yoke'37 is loosely mounted upon the driven shaft 7 the end 38 thereof, being arranged within the tank and adaptedto engage thesleeve 31 so as to shift the sleeve upon the driven shaft which in turn, will push the rack bars through the medium of the rods so as to cause the arms carrying the brushes to be thrown outwardly. A suitable bracket 39 is mounted on the tank and. carries a lever 40 which is connected to the yoke 37 and is supported at its free end by a guide bracket41 as clearly shown in Fig. l. The free end of the lever 40 is connected to abell crank 42 mounted upon the side of the tank by a rod 43 the opposite arm of said bell crank being connected to a trea'dle 44 mounted upon a stud projecting from one of the legs of the tank by a rod 45 and it will be seen that when. the 'treadle is pushed downwardly by the operator exerting a pressure thereon with his foot, the crank will be rocked and through the medium of the connecting rodand lever, the yoke will be shifted upon the driven shaft.

In order to return the treadle to its nor-' mal position, I arrange a bar 46 on the outside of the tank having a hooked end to which is connected one end ofa' coil spring 47 the opposite end being connected to the bell crank 42 as clearly shown in Fig. 1.

It will be seen from the construction so' far described, that-I have provided an expansible head to receivea can to be washed having brushes which are so mounted therethe tank, brackets 48 and 49 in which are mounted parallel curved levers 50 and 51 the free ends of the levers 50 being connected together by a brush 52 and the free ends of the levers 51 being connected together by a brush 53. The levers are loosely connected asshown at 54 so as to rock together where bythe tWo brusheswill be thrown simul taneously into engagement with the outer tensions. 55 to which are pivotallyconnected operating rods 56 whichare mounted in suitable bearings 57 "'adjacentth'eir' upper ends- The free ends of saidrods extend .through openings 58 formed in the cover 3 raised po'sition; which in turn will hold the brushes out of contact with the can. It will beseen by this construction, that the outside brushes are normally out ofthe path of the can when being inserted or removed.

The tank is provided with bearings 60 in which are pivotally mounted the arms of a frame 61 which carries a brush 62 adapted to pass down through the opening of they cover 3, said frame being normally, held in a raised position by a coil spring 64 as clearly shown in Figs. 1 and 4. The arms of the frame 61 are arranged in vertical'alinement with the projecting ends of the operating rods 56 so that when the frame 61 which is provided with an operating handle 63 is forced downwardly by exerting a pressure upon said handle, the arms will engage the ends of the operating rods 56 so-as to rock the levers which in turn will move the brushes into engagement with the outer face of the can, it of course, being understood that the brush 62'is simultaneously brought into engagement with the can.

In order to provide means for washing the bottom of the can, I arrange within the tank a suitable rock shaft 65 which has an arm 66 connected thereto carrying a brush 67 which is preferably shaped so as to'conform to the outer surface of the bottom of the can, said shaft 65 being provided with a crank 68 to' which is connected a link 69 said link being connected at its free end to an angular lever 7 O mounted upon a pivot 71 arranged in the side of the tank and guidediby a suitable guide member 272 the V throw the brush 67 into and out of engage ment with the can. The tank 1 is of sufficient length to allow a can to be readily inserted or removed therefrom and it will be upper end of said leverbeing provided with seen that by placing the-can ina horizontal position within the tank and forcing the same onto the expansiblehead, the same will be supported by said head and by operat ing the treadle 44 the head can be expanded so as toexert a pressure on the inner sur-' the can to such an extentithat the face of can" Wlll'zb carried with the head and by.

' pressing downwardly on the handle 63 and Y can. vAfter the can hasbeen thoroughly shown in Fig. 1.

washed in thismanner,,-the sameisremoved- I from the expansible head and placed upon a rinsing sterilizing device 73 arrangedat the opposite end of the tank 1 as clearly From the foregoing description, it, will be seen. that I have provided a can washing machine in which provision is-madefor exer-ting, pressure upon the; respective brushes so as to holdthe can when rotating, at the operators will, thereby allowing one set. of brushes to clean either the outer or inner surface as the case may be, while the can is held stationary by the other set of'brushes.

It will also been seenthat the brushes are so constructed that they conform to the conformation of the well-known form of cans now in use so as tothoroughly clean all of the surfaces thereof.

V In the operation of my improved construction of can'washer, the tank is partly filledv with; water so that thefcani will be partly submerged when being washed and while in the drawings, I have failed to show any inlets and outlets for the tank it is, of course, understood that suitable ports can be providedxfor' filling and emptying the tank.
